Question

A bird is in a wire cage hanging from a spring balance. The reading of the balance is taken when the bird
flying about in the cage, and when the bird is at rest in the cage. The first reading will be
A) Less than the second
B) Greater than the second
C) Much greater than the second
D) Same as the second

Answer 1

Answer:

greater than the second

Explanation:

because when the bird was at rest the spring balance was measuring the weight of the bird as well as the cage.. so when the bird began to fly then the balance wasn't measuring the weight and so the reading being shown by the balance was less

Answer 2

option B is correct greater than the second
